Hello all,
arduino 2560 mega, ramps 1.4, running marlin.
I have a cooblebot printer that I am having trouble making the z motor go up, it only wants to go down.
I have tried switching the wires around both ways and I have tried changing the code to say true invert the z axis instead of false.
1: code false, wires right way up.
2: code false, wires wrong way up.
3: code true, wires right way up.
4: code true, wires wrong way up.
I have now tried all four of these combinations and all are still resulting in the z axis traveling down..
Any ideas would be greatly appreciated.. as I am at a complete loss..
